Chances are you already either have a USB \"thumb\" drive, or you will have one in the near future--these little solid-state flash memory devices are inexpensive, nearly ubiquitous, and very, very handy. Not only can they replace floppy drives for casual file transfers, but the larger capacity thumb drives also can serve as the basis for an excellent, fit-in-your-pocket software repair kit, letting you diagnose and repair PCs, including those that might otherwise be unbootable or that are locked by password or other problems.

We've discussed USB drives before in \"What's Behind The USB Drive Revolution\". We also looked at ways to make a USB drive bootable from DOS in \"Solving USB Boot Problems\". We've also mentioned ways to boot from Linux (such as is discussed in this HowTo or in this Google search.) If you missed either of those earlier articles and references, this would be a good time to click back and catch up so we'll all be starting on the same page.
But when we left off our discussion of USB drives, there was no good way to boot XP from a thumb drive because of the way that XP takes over USB control as the operating system starts -- in effect, XP tries to take over the USB system it's already using to boot from, with unpredictable results.
